Geodata comprises of information on proportional shares of geological units in the catchment, the average slope in the catchment and the catchment area upstream of each site. Data from ID values CG 12 to CG 18 were derived from discharge values measured by the Luxembourg Institute of Science and Technology (LIST). Data from ID values CG1 to CG11 were de-rived from water level data measured by METER/Decagon CTD pressure transducers in stilling wells. EC values were classified into no-flow situations for EC-values below 25microSi/cm and flow situation for EC-values above 25microSi/cm.Ĭonventional Gauges are divided into two sub-datasets. Onset HOBO Pendant waterproof temperature and light data logger (Model UA-002-64, Onset Com-puter Corp, Bourne, MA, USA) with modified light sensor to measure electric conductivity were used to monitor electric conductivity (EC) as proposed by Chapin et al. This method was closely related to a time-lapse camera gauging system published by Gilmore et al. ![]() For improved image analysis a gauging plate was installed in the channel. Cameras were mounted at trees or structures close to the channel. Time lapse mon-itoring was realized with the internal software with a temporal resolution of 15 minutes. ![]() Methods Time-lapse Imageryĭörr Snapshot Mini 5.0 consumer wildlife cameras were used for time-lapse imagery. It can be used to test and evaluate hydrologic models, but also for the assessment of the intermittent stream ecosystem in the Attert basin. The dataset features data from catchments covering all geologi-cal characteristics from single geology to mixed geology. The catchment covers three predominant geologies: Slate, Marls and Sandstone. Hydrological regimes are mainly driven by seasonal fluctuations in evapotranspiration caus-ing flow to cease in intermittent reaches during dry periods. Climate conditions across the catchment are rather similar in terms of temperature and pre-cipitation. The elevation of the catchment ranges from 245 m a.s.l. The Attert basin is located in the border region of Luxembourg and Belgium and covers an area of 247 km². ![]() The dataset provides valuable information of the dynamics of a meso-scale stream network in space and time. Each single dataset was carefully processed and quality controlled before the time interval was homogenized to 30 minutes. Temporal resolution ranged from 5 to 15 minutes intervals. (2013) while the setup for EC-sensor was proposed by Chapin et al. Setup for time-lapse imagery measurements was inspired by Gilmore et al. The first sites of observation were established in 2013 and successively extended to a total number of 182 in 2016 as part of the project “Catchments As Organized Systems” (CAOS, Zehe et al., 2014). We used different sensing techniques including time-lapse imagery, electric conductivity and stage measurements to generate a combined dataset of presence and absence of streamflow within a large number of nested sub-catchments in the Attert Catchment, Luxembourg. ![]() The time series did not change and are not included in the V1.0 zip folder. The version 1.0 is available in the "previous-versions" subfolder via the Data Download link. This version includes additionally the catchment boundaries provided as subfolder of geodata.zip.
